Sunan an-Nasai
أَخْبَرَنَا أَبُو عَمَّارٍ الْحُسَيْنُ بْنُ حُرَيْثٍ، قَالَ أَنْبَأَنَا سُفْيَانُ، عَنْ عَمْرٍو، عَنْ عَطَاءٍ، عَنِ ابْنِ عَبَّاسٍ، قَالَ إِنَّمَا سَعَى النَّبِيُّ صلى الله عليه وسلم بَيْنَ الصَّفَا وَالْمَرْوَةِ لِيُرِيَ الْمُشْرِكِينَ قُوَّتَهُ .
It was narrated that Ibn Abbas said: "The Prophet walked rapidly betwwne As-Safa and Al-Marwah to show the idolaters that he was strong."
